I PR EM NT m MACHINE r012 SPLITTING WHALEBONE.

Th schedule referred to' in these Letters Patent and making part of the same To 11 mm; to whom thesc jn'csents may come Be it known that I, JAMES A. SEVEY, of Boston,

of the county of Suliolkhnd State of Massachusetts,

have madea new and useflllviuvention having rcferf sectionbeing' taken between its throat piece adjusters.

The principal ohjectol' the machineyis to effect the reduction of a strip of whalcbone to two ormore smallcrjstrips, having.rectangular-or square transverse sections, and generally with parallel opposite sides v In the drawing-5 A denotes the standing frame of the machine, it being provided with two parallel arms 13 B, projected from and arranged sons to turn vertically on a -shaft, 0, extending through theposts of the frame. i i

Olamp-nutsa a scrcwed on the shaft, serve, when screwed up against the arms, to force them up to shoulders of the shaft, and to thereby hold the arms in either a horizontalor inclined position, as'may be desirable; I p v .A bar, D, extends from one of the said arms to i theother, and at its ends is securely fastened to the two: i

Arranged parallel to the; bar D. is anothersueh .har, E, which is suspeudedl'from the arms B B by means ofvertical projections or ears I) 7), arranged to slide. on the arms B B,-and provided with clampbolts 0 and nuts (I to fixthern to the said arms.

There is a slot, 0, in each of the arms, such slots being for reception of the bolts.

, i 1 Between the two bars D E there are arranged two other such bars/F G, each-of which is provided with adjustments by which it maybe moved atits ends, either toward or away from its fellow bar.

These adjustments consistpin part-,oftwo slotted teuons or projectionsf j, which extend from each of the bars F G,"aud go through the next adjacent ofthe bIJIISDE. a

A clamp-screw, s, goes through a slot in each projeetion j, and screws into the" next bar D or E, and 1 serves to clamp the projection to the bar.

series of knife blades, K K, 8:0.

enceto the knii'c,-in manner as represented Circular passages are bored or formed through all the bars E F G H, to serve as bearings for the pairs,

of cylindie-segmental lmife-carriers.

These knife-'carriers are represented at I 1'. Each is a cylindrical segment, nearly semi-cylindrical iu shape, the versed sine of half the arc of its segmentalsection being equal to the radius of curvature minus one half the thickness of the knife to be held between each pair of these segments. T i i These knife-carriers, arranged within the circular passages orbearings of the bars 1) E F G, in manner as represented in the drawing, serve to support a Each of these blades goes transversely through the said bars, and is supported on themv by four of the carriers, the same beingso that, by revolving theear-' riers more or less, the inclination of the blade transversely to the horizon may be'varicd and determined. as circumstances may require.

To each pair of the carriers there is a elamp-scre\v, h, for holding the pair in. position, such screw being screwed up -into that bar I) or E, within which the pair may be situated.

In Letters Patent No. 91,047, dated June 8, 1869, andgrauted to me, I have described vand vclaimed analogous carriers, bearings, and clamps, for support iug and adjusting a knife for splittingwhalebone.

I By'ha-ving the bar E movable, relatively to the bar D, I am enabled to adjust the guide-bar G at such distance from the guide-bar F as may be desirable, according to the width of the strip of whalcboneto be operated on.

To'each knife there is a throatrpicce, L, which is ahar or rod of mctalfit being arranged, with refer- It goes through mortises madein the several bars D 'E F G, and is held in .place by-means of clamp-screws 'i i,

"screwed up into the bars, and against it.

. To hold the throat-piece securclyin place when the guide-harsh and Gr are made of wood, I employ thin plates or bars k 7:, of metal, fastened to the inner sides of the bars F G, and notched to receive the throat-pieces.

It was hereinbeforestated that each of the bars F G is provided with two slotted teuons or projections f f. They enter recesses u u in the ends of the bar. v

Each .tenon is connected to the bar by a screw, as shown at t.

By slacking or turning back one of these screws, and correspondingly tightening "or setting up the other, an cndwise movement maybe imparted to the bar.

These endwise movements of the two bars are for Wa t.)

frameA, so asto be capable of turning vertically thereon.

the purpose of moving the throat-pieces either nearer to or further from the knife-edges, as occasion may require.

The lateral adjustment of. each of the bars F; G is to enableit to be moved either toward or away from its fellow bar without the necessity of disturbing the'clamp-screws, by which the knife-carriers and their knives are held in place. I

Furthermore, there is a frame, M, arranged over the space between the guides 1* G.

This frame is pivoted 'to the middle of an adjust-able cross-bar, N, so as to be capable of being turned in a vertical plane passing transversely through the machine.

The pivot of the frame M is shown at l.

The pivot may be arranged in a slot in the bar N, and may be provided with a clamp-nut, to fasten it in position in such slot.

The slot in such case should extend lengthwise of the bar, in order to cnahle the frame M, with the pivot, to be adjusted in directions lengthwise of the frame, in order to aid in effecting the proper adjustment of the pressure-rollers relatively to the knives.

The bar N has two slotted ears 0 O, which project back from it at right angles, and against two arms I P, which are pivoted to the shaft of the Each of thearms l is furnished with a curved fork, Q, to embrace a clamp-screw, It, arranged'in the next adjacent bar B, the whole being to enable the frame M tol-be adjusted and held in position relatively to the several knives, or at the proper distance therefrom, as circumstances may require.

The said frame M supports or carries a series of vertical slides,m, each of which is furnished with a helical spring, a, to press it downward, a screw, 0, being-employed, in manner as represented, in connection with the spring, tocontract such spring, as occasion may equire, in order to increase its elastic force.

To eachof the said slides a wheel-carrier, p, is pivoted or hinged, in manner as shown in the drawing, the same being so as to enable the said carrier to swing in a plane longitudinally of the machine.

A roller or wheel, q, to revolve in ,a plane transversely of the machine, is arranged in and pivoted to each of the carriers 1), there being one of such rollers to and over each of the knives.

By means of the application of the arms B B to the shaft 0, so as to turn thereon, as described, we are enabled to readily invert the arms or turn them through a half circle, in order to conveniently-gain access to the'clamp-screws of the knives, and their carriers.

The clamp-screws of the throat-pieces also admit of each of the said throat-pieces being adjusted out of parallelism, or somewhat oblique to its knife, in order that the knife, while in operation, may be caused to separate from the strip of whalebonc a strip which may be wedge-shaped.

On the lower bar of the frame M there is arranged a slide-bar, S, provided with ears a a, extending down from it over and against the front edge of the said lower bar.

Clamp-screws b I), going through slots in the ears, serve to clamp'the slide-bar to the frame.

There are also adjusting-screws c 0' arranged in the end bars of the frame, and against the ends of the side bars, these screws being to efi'ect a movement or adjustment of the bar endwise.

The bar S, shown in top view in Figure 6, is provided with a series of notches, d, to receive and'guide the several slides m.

In the lower bar of the frame M, and below each forced and drawn along between the guides F G, so-

as to be driven into contact with the series of knives.

The advancing end of the strip meets the cuttiug-- edge of each knife in succession, and, as each strip is separated from the main piece,such strip will pass through the knife throat, and will finally drop out of the machine.

By putting together, side by side, a series of such strips, and. running the whole, with their edges upward, through the machine, each of the strips may be divided into several smaller ones.

It should he understood, however, that while the strip is being operated on, the series of presser-wheels q is to be over and borne down upon the strip, so as to cause it to take the knives successively, and maintain its proper relation with each while it may be in operation. 1 1

Each of the throat-pieces, by being'in the shape of a long rod, may, from time to time, be moved endwise, as it may become worn.

In this way a fresh or unworn portion of the throatpicce may be brought up the knife, as circumstances unay require.

Each of the prcsser-wheels g, by being supported in a carrier, 1), pivoted or hinged, as described, to a slide, m, is rendered capable of moving laterally more or less, to conform itself to the upper surface of the strip of whalebone. This is an important feature of the machine.

The thin plates or bars 7; k, fastened to the bars 1 and G by screws, not only perform the function of holding the throat-pieces securely in place, but they serve to enable the throat-pieces to be arranged at the proper distances apart, relatively to each other, to cause the bone to be cut smoothly, and in other rcspects as may be desired. 4

It is often the case that some parts of the bone, in order to be properly split, require the throat-pieces to be nearer the knives than is the case with other portions of the bone. I

Thus it will be seen that, with a series of the plates It k, having their notches arranged for different grades of bone, so as to bring the throat-pieces into the proper relations with the knives, as each grade or quality of bone may require, we have an advantage which results from the employment of these plates.

I herein make no claim to anything, combination or arrangement of parts, as represented or described in the United States patent No. 70,545, dated November 5, 186,7, meaning specially to make no claim to adjustable rollers, in combination with a series of knives and an adjustable throat-piece, as described in such patent. I employ, instead of rollers, rods or bars, so applied in the frame as not to be capable of revolving as rollers, though capable of being moved endwise, and being fixed therein, as and for the purpose hereinbeforc explained.

In the above-described machine I claim as my invent-ion, the following, viz:

In connection with llll6' bfllS D E, when. combined. and arranged with a series of knives, substantially in manner as described, mechanism, as set forth, viz the hangers b b, the slots co, in the arms B B, and the clamp-bolts and not 0 d, by which. the'said bar E may be adjusted and fixed in position, either nearer to or further from the bar D, as circumstances may require,

Also, the combination and arrangement of the throat-pieces, carriers 1 G, provided with the bars ,1) E, and the series of knives K, applied to the latter.

'Also, the bmbination and arrangement of the series of throat-pieces or bars L, made soas to be capable of being moved endwise, as and for the purpose'described, with the series of knives K and the bars F G appliedto thebars 1) E, asset forth.

Also, the combination [of the additional throatpiece supporters k k withthe main supporting and guide-bars F G applied to the bars D E, as described.
